I understand that The Walking Dead has a bulging cast, and I understand that they're all scattered in different places, but considering the entire episode was based in Alexandria, it's crazy how many key characters were completely omitted from the mid-season finale. Heath was a cool character when he was introduced earlier in the season, Aaron has really grown in recent episodes, and Spencer... Well, he's Spencer, he's an idiot, but that doesn't change the fact that he's also in Alexandria. First, did they all survive? Second, where are they? Third, how big are their roles going forward?
